The orgasmic brain exposed: results from PET-studies in men and women

Janniko Georgiadis

There is still a lack of knowledge regarding the brain regions involved in human sexual behavior in general, and orgasm in particular. In the last five years, we have performed a series of positron emission tomography (PET) experiments in healthy men and women to investigate the neuronal substrate of the orgasmic phenomenon. Orgasm-related brain perfusion appears to be similar in both sexes: compared to a baseline of sexual genital stimulation (high sexual arousal), orgasm-related activation was found in the medial part of the anterior cerebellum. Interestingly, orgasm-related deactivation was much more prominent, especially in the orbitofrontal cortex and the anterior temporal lobes.
